BREAD-FANS.

Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, JAMEs E. LEAMANN, a citizen of the UnitedStates,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Bread-Pans, of which the following is aspecification.

This invention relates to an improvement in bread pans for use in bakersovens.

One object of the invention is to provide an im roved-constructionwhereby a number o' single-loaf bread-pans may be connected together inseries and each two endpans of the series have protected outermostwalls.

The invention is shown in the accompanying drawing in which- Figure 1 isa view of a series of individual bread-pans connected together andhaving my improvements. Fig. 2 is a side view of the end-pan of theseries. Fig. 3 is a longitudinal section of the reinforced side of a pantaken on the line 3-3 of Fig. 2. Fig. 4 is a cross-section of theimproved bread-pan.

The drawing shows rectangular bread-p ans each for one loaf of bread;these ans are commonly made of a sheet of metal shaped to form a bottom,5, two end walls, 6, and two side walls, 7. The corners of the pans areformed by V-shaped folds, ,8, which ordinarily have position on theends, 6, of the pan. The bottom and all four walls of the ordinary panonly have one thickness of sheet-metal.

In Fig. 1 which shows four pans connected together, the two pans, B, B,which are intermediate of the end pans, A, are made in the ordinarymanner just described. The two end pans, however, of the four pans shownin Fig. 1 have one side wall, 7, single thick and the opposite side walldouble thick.

Referring now to the pan shown in Figs. 2, 3, and, 4, it will be seenthat one side wall consists of a single thickness, 7, and the oppositeside wall consists of two thicknesses, 7, 10. The two thicknesses areproduced by adding an outer thickness, 10, to the inner thickness, 7,and securing said outer thickness to its position; the outer thicknesscomprises the reinforcement herein-before mentioned. In this reinforcedpan, A, the V- shaped fold, 9, at each corner is folded over and lapsupon the end of the side-reinforcing plate, 10; these folds produce fourthicknesses of metal at the side adjacent the cornor as seen in Fig. 3.As the pans have inclined or flaring walls, and'as the two end edges ofthe said outer plate, 10, are inclined to correspond with the flare ofthe end of the pan, it will be seen that said V-shaped folds, 9, serveto hold the plate, 10, in its proper position especially as the topedges of all the walls are coiled over outward,the coil, 11, of the sidewall being in contact with the upper edge of the said plate, 10. Forfurther security in holding the reinforcing plate, 10, a rivet, 15, maybe employed; this rivet passing through all four thicknesses.

In order to still further increase the stiffness of the outermost sidewall of the endpans, the outer thickness, 10, of said wall is providedwith several vertically-extending outward swages or protrusions, 12.These are formed, before the plate is attached to the pan, by means of adie pressing the metal outward. The several pans are secured together bybars, 13, extending along each end of all the pans of the series, andthe ends of said bars bent at a right-angle, 14, and said bent endsprojecting around the corner and overlapping on the double-thick side,and the rivet, 15, passed through said bent end, 14, and also throughthe four thicknesses of sheet-metal where the fold, 9, is located. Thiscombination and arrangement give the desired strength to the series ofpans and reinforces the side of each end-pan.

Having thus described my invention what I claim and desire to secure byLetters Patent is,

1. The combination of a series of rectangular bread-pans, the twoend-pans of the series each having its outermost side-wall composed oftwo thicknessesthe inner thickness having an interior surface which iscontinuously straight from end to end and the outer thickness providedwith exteriorlyprotruding and vertically-extending swage marks, and theinnermost side-wall of the end-pan composed of one thickness only ofsheet-metal, and the one or more pans of the series which areintermediate of said two end-pans having walls of one thickness only,and means extending along all the pans of the series and securing themtogether.

2. The combination of a series of sheetmetal bread-pans in contact witheach other, and two end-pans, A, of the series each having one side-wallof one thickness only and the opposite side-wall of two thicknesses seiV ,wg hta U ma cured together said two thicknesses constisaid twothicknesses of said end-pans and setuting the end or outer side of theseries, and cured thereto. in the -pans, B, of the series Which areinter- In testimony whereof I affix my signature mediate of saidend-pans having all their in presence of two Witnesses.

Walls of one thickness only, and metal bars 1 JAMES E. LEAMANN.extending along each end of all the pans of l WVitnesses: the series andthe ends of said bars bent and OHAs. B. MANN,
